` CORPORATION OFYNEW YORK BATTLE ORDER INSTRUMENT Application led December 29, 1921. y vSerial No. 525,594.

This invention relates to signalling devices, and more specifically to battle order instruments for use on warships for the transmission of orders or information from a fire control station to the vicinity of the guns or torpedoes for the benefit' of the `gun The principal obgects ofthe invention are `to rovide a device of this character which wil possess a high degree of reliability; withstand rough usuage and at the same time be il.: t.

of comparatively compact arrangement. i Other objects will appear in the following specification of the invention.

Referring to the drawings wherein l have shown what I now consider to be the preferred form of my invention:

ings, the transmitter casingis shown at 1 ofhandles on the outside of the casing the Y with a cover 2 secured thereon by bolts 3.

`Withinthe casing arethe transmitting control elements adapted to be actuated by means said control elements may include switches 4, V5 having central spindles 6, 7 reaching without the' top of the casing and having apparatus would tend :to

handles V8, 9 fixed thereon.. Saidspindles are shown as projecting through bossesllO, and

`may be provided with packing 11to prevent leakage of moisture or air along the spindle and into'the casing. A grease cup 12 may be connected to the boss to supply lubricant to the `packing to serve the double purpose of enhancinorr the water-proof or lair-tight qualitiesl of the packing and, of lubricatingthe spindle in its bearing In connection with one of the bearings I have shown washers 11a pressed into position bya spring 11b. The grease may then be pressed into the space in which the springworks to render the point more perfectlyproof against leakage, so that in the event that a partial vacuum is created within the casing 1, the same `may be maintained. An important reason for y atmosphere, and the heat caused by the electricl coils within the casing causes the air .therein to expand and force its way out through the oints, subseientcooling ofthe e followed by suction of air `into the casing, and the accompanying moisture would tend to cause corrosion `or other bad effects upon the deli'-V cate metallic parts of the instrument; The

switches Yare shown in greater detail in Figs. 9 and 10. The spindle 6 carries rigyidly secured thereto insulation 13 to which `are fixed two conductor rings 111, 15.

Said rings are provided with extensionsl, 17 reaching over and forming arcs in the periphery of the central and raised portion of insulation 13. A plurality of brush contacts18 secured to posts 19 engagesaid periphery and arcs, while brush contacts 20 ses cured to posts 21 engage rings 14 land 15. Posts 19,21 are carried by memberV 22 mount-V ed on a plate 23 which is in=turn attached to the cover 2 by posts 23.A Rotation of spindle `6 will vary the combinations: of contacts madebetween arcs 16, 17 and brushes 18. Posts 19, 21 may be of conductingmaterial terminating in contact plugs 24, and may` ,be supported near their lower ends by a member 25` which may also serve as a bearing for the lower end of spindle 6. Secured to .27 .the receiving .instrument The `details of thisrnotor are niorelspecifcally set forth in the""`patents to Elmer A. Sperry, Jr. for Electrical transmission systems, No. 1,603,646, granted October 19, 1926, andlfor `Repeater motors, No. 1,605,571, granted November 2, 1926, and need therefore only tobe `briefly described here.,l Referring to .Figs 7 .and 8,

' after station, the receivers `may be connected towboth transmitters and a suitable switch provided for connecting the receivers tothe desired sta-tion.

In the receiver I have shown an indicator card 66 havin the designations Forward, Local, and After marked thereon. The card may be secured through an arm 67 to a magnetic device 68. Corresponding to this in the transmitter is a card 66 bearing the references F, L a-nd A. This card may be secured to a magnetic device 68. 1 This. device which may be similar :to device 68 is more clearly shown in Figs. 5 and 6. The arms 67 which carries card 66 may be pivotally supported at 69 to a top plate 70; the latter being removed inFig. 5 to reveal the other elements. Secured to and projecting downwardly from said armis shown a soft iron bar or armature -71 adapted to cooperate with the poles 72 of electro-magnets 73, 74. A flat spring 75 engaging the straightrear end 67? of arm `67 1s provided to hold `the card 66 normally centralized so that the L is visible through the window 76 (Fig. 1). When magnet 7 3 is energized the card will be moved to that side as shown in dotted lines 77 (Fig. 5) and the A will obviously appear in the window, and energization of magnet 74 will render F visible. As

in the case of the transmitter switches, the magnet device may be provided with contact plugs 78 adapted to engage receptacles 79 in casing 1 when the cover 2 is in place; the

device being attached at 80 to said cover 2. Associated with said magnets is a switch 82,

the details of which are shown in Figs. 3 and 4. This switch may comprise a stem 84 on which the handle is mounted reaching through cover 2 to the inner side thereof and carrying a drum 85 having a contact 86 adapted to cooperate with either of contacts 87 88 when rotated in one direction or the other. Also fixed on said spindle 1s a wheel 11 89 having three notches 90 cut therein and engaged by a projection 92 on a spring pressed lever 93. The projection will thus serve to hold the switch in the position to which it has been turned. The switch is secured by screws 94 to a boss 95 on the inside of cover 2. The switch handle 95a'may be!V provided with a projection 95b (Fig. 2)

adapted to engage stops 96 on the boss 96 through which spindle 84 passes, to limit the extent that the switch may be turned.

In Fig. 13 I have shown a wiring diagram n which may be'employed where there are `two control stations. The switch 81 may be located near the device 68 at the gun; while device 68 and switch 82 are in the forward:` control instrument and device 68 and switch 83 are in the after control station. The

switch81 may be normally in the position shown; the forward stationbeing in control andthe after station being cut out. If the oicer at the forward station is to control the firing he communicates this information tolr the gun by turning switch 82 to close contacts 86-.8 the positive side of the feed lines 97, through switch 81, line 98, contacts 86, 87, line 99, coil 73, lines 100, 101, coil 102, and line 103 tothe negative side of the feed. Thus coils 73 and 102 will be energized resultingin positioning the designation Ford` in the window 104 of the receiver, and F in window 76 of the transmitter. The positioning of the indications in th-e transmitter window will indicate to the control othcer that the apparatus is functioning properly.

ceive orders from the after station the oiiicer at the forward station will turn switch 82 to close contacts 86--88 The w-ord After will then appear in widow 104 and the letter A in window 76. The gun crew, will, ,uponl receipt of this order throw switch 81 to conneet the receiver with the after transmitter.-

All orders thereafter received will come from that station. 'It will, ofcourse, be understood that the throwing of switch 81 will connect This will complete a circuit from.

i If itis intended that the gun `crew shallV re` all elements of the receiving instrument with i the forward or after control station asthe case may tbe. The designation Local on= th-e card 66 Vof the receiver and the L on card 66 of the transmitter serve to instruct the gun crew to assume local control in operatingthe gun. This position as we have seen will be assumed whenever there is no current flowing. Thus, should the connection with the control station be shot away or otherwisev destroyed the gun crew would be automatically instructed to assume local control, and the oicer stationed at the gun in chargeof the gun crew would control `according to his own judgment.

In Fig. 1 I have shown several switches 82 and corresponding indicators 76, similar to switch 82 and indicator 7 6. Each of these may be connected to a separate receiver so that any gun or groupof guns may beinstructed to receive orders from the after sta-` tion or to assume local control while others are retained in control of the forward station.

`Positioned in thelower right hand corner of` the' receiver I liaveshown; an indicator" card105 bearing designations designed to instruct the gun creiv, when in one'position, to follow! the' pointer in trainingthe gun, in which case' the gun Will bei trained to coin? cide'witl1` pointer controlled from a distance andkept pointing in the direction of the target The latter instrument forms no part of thepresentv invention and is therefore not shownhere. In another position the card y Willinstiuct the gun crew that the gun isto i fai be lired by the director firing system. '-And when? in the centraly position with the Word Fointer477 in the YWindow 106 the-gunners i?? will be instructed tov do all` aiming through the regular sighting' elements. The construction of In'agnets'107 with the card 105 may be thelsanije asgdisclosed in Figs. 5 and 6., The' switch 108 in the tralisrnitter which controls. theseniagnets'niay inturn be the same as that disclosed infY Figs. 3 and 4. fTh'e Wiring diagrain shownL in Fig. 12`inayalso serve in this insta-neer The indicator card 105 in the i transmitter, however, is here shown as conf5; nected` directly tothe spindle 109 of switch 108 at' 110 and is visible through Window 111.

At `1112 and 113 in the receiver I have shown additional' indicator cards actuated byelectrosmagnetslllt, 115; These magnets *i* and `@was are Controlledbyvswaches 116, 117

The card 1121s designed to instruct the gun crevvfasto the typeof shell to be used,"whil e c cardV 113 instructs the` gunners to fire or to cease firing, and in its centralized position indicates that theV circuit isbroken; If, duringoperat'ions, neither the order to fire nor toc'ease iii-ing is visible through vvindo`vv1'19,v

the `information that the circuit?V is broken will appear.` The gunners will then,ivhere two stationsl are provided throw `svvitch 81 (Fig- 13)` to pick up theafter control'station? `If butr Onestation is provided or` the 'c'rcliit'reniains broken WhentheV after station isthrown in, the gun crew will assumefull controlfiniring the gun as in the case Where tiielocal control order is given. y
